Abstract: In order to solve the problem that the producers can′t quickly distinguish the products with naked eyes when the CNC cutting machine cuts the products with similar shape and small area, a control system integrating ink-jet, pen drawing and cutting is studied. A set of upper computer control system application program is developed based on MFC, and combined with the lower computer motion control system based on STM32, the product information is finally sprayed and painted on the product, which is convenient for producers to quickly identify the product. The feasibility of the system design is verified by the application of clothing sample, which meets the actual needs of production.
